说明：  Copula函数，以及相关性计算和相应的散点图(Copula compute)

空间面板，直接和间接效应，LM检验,包括例子，代码等等。(The demo contains files to estimate all spatial econometric models based on an exact calculation of the Jacobian term in the log_likelihood function. Supporting files to print the results, to calculate (robust) LM-test statistics and to calculate direct and indirect effects are also included.)

R-NSGAII的文章及matlab源代码，亲自实验能运行，对研究多目标很有帮助(R- NSGAII articles and matlab source code, experiment can run in person, is very helpful for research object)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.

pwm半桥逆变,经典案列，经测试没问题，运行很好。PWM half bridge inverter, the classic case, tested no problem, the operation is very good.(PWM half bridge inverter, the classic case, tested no problem, the operation is very good.)

this programs are educational

使用matlab写了一个很有意思的程序 大家看看作为参考(Use matlab write a very interesting program we look at as a reference)

DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.

关于惯性导航系统的使用工具箱,包括了各种函数的编写及使用说明，最重要的是先要安装此工具箱。(the toolbox is very good ,and it s about INS .)
